Profile: Acquired from the Cardinals for Pedro Feliz in August 2010, Carpenter made his big league debut in 2011 and was quietly effective down the stretch for the Astros. He struck out 29 and walked 13 in 27.2 IP, but the walk total is inflated by seven (!) intentional walks. His Minor League walk rate since the start of 2010 (2.68 BB/9) gives us a better idea of what lies ahead, and he's always been a strikeout-per-inning guy. Carpenter is a fly ball pitcher in a hitters' park, so homers will be a concern, but there's a lot to like anytime a guy legitimately sits in the mid-90's with a power mid-80's slider. The closer's job in Houston is wide open following the trade of Mark Melancon, and Carpenter is a definitely darkhorse for the job. If he doesn't get the ninth inning, he's still a prime candidate for holds and useful in all ottoneu formats. (Mike Axisa)

The Quick Opinion: Don't be fooled by Carpenter's intentional-walk-inflated WHIP (seven of 13 walks were intentional), the hard-throwing righty has a chance to pick up plenty of strikeouts and holds for the Astros next year. He's also a darkhorse candidate for saves.

Profile: David Carpenter may have been a great reliever in the minors, but he’s struggled in the majors, and now he’s buried in the Braves’ depth chart. Stay away. (Zach Sanders)

Profile: The Braves claimed Carpenter off waivers after the 2012 season, which saw him post a 8.07 ERA with below average peripherals (4.62 xFIP). He spent April and part of May in Triple-A, where he showed improved command and control. Those gains remained upon a promotion to the Atlanta bullpen and were accompanied by an excellent strikeout rate. The 28-year-old struck out over 10 batters per nine (10.14 K/9), held hitters to a .260 batting average on balls in play, and stranded over 90% of base runners. That trio of stats might have been a bit fluky for Carpenter, which explains why his 1.78 ERA doesn't jive with his 3.11 xFIP. Owners looking for a good holds reliever should still consider Carpenter. He only accrued 12 last season, but he gained increased trust throughout the season and will probably open the season as the seventh inning reliever. (Brad Johnson)

The Quick Opinion: Carpenter broke out in 2013 thanks to improved command and control. He upped his strikeout rate while nerfing his walk rate, a combination that helped him to a stingy 1.78 ERA. He probably won't be that good next season, but he's a good bet to be above average.

Profile: Though his ERA jumped last year, Carpenter proved to be quite the waiver-wire find for the Braves. Now, Carpenter has been traded to the Yankees along with Chasen Shreve for a former top prospect in Manny Banuelos. Although he has a lot of strikeout potential, he is too far down the saves totem pole for the Yankees to be relevant in fantasy leagues. (Ben Duronio)
